Technology after WWll advanced greatly due to entering the atomic age. Following the bombings on Hiroshima and nagasaki, the U.S. entered the war in Vietnam where we used napalm bombs to burn down the forest because we found out that the Vietnamese were hiding in the trees. Then a couple years later the Cold War started and the U.S. built a huge amount of nuclear weapons at the same time that the Soviet Union was building nuclear weapons luckily we didn’t break out into war but there were a couple of times where we almost did. Now social media changed after WWll by creating even more political cartoons describing everything that’s happening in a single comic strip. Nowadays the whole world makes memes about previous and current wars that had happened or are happening right now.
